Researchers from NYU Langone Health found a key protein called HOXD13 that helps skin cancer grow and avoid the body's immune defenses. They discovered that this protein boosts blood supply to tumors and weakens the immune response.

Scientists have long been searching for ways to stop skin cancer from growing and spreading. Now, researchers at NYU Langone Health have made a breakthrough discovery that could help us do just that. They found a molecule called HOXD13 that plays a central role in melanoma, the most aggressive form of skin cancer.

HOXD13 helps control how genes work together to build and maintain our bodies. The study showed that this protein is crucial for forming blood vessels that supply tumors with oxygen and nutrients. This process is called angiogenesis.

The researchers found that HOXD13 activates several pathways that increase blood flow to tumors. When they reduced HOXD13 activity in experiments, the tumors became smaller. They also discovered that melanoma patients with high levels of HOXD13 had fewer cytotoxic T cells in their blood. These immune cells are responsible for identifying and destroying cancer cells.

The team found that HOXD13 alters the environment around tumors in a way that weakens immune responses. It increases levels of CD73, which raises levels of adenosine. This substance acts as a protective barrier for tumors by slowing down T cells and preventing them from entering cancerous tissue.

The study's lead investigator, Pietro Berico, said, 'Our study provides new evidence that transcription factor HOXD13 is a potent driver of melanoma growth and that it suppresses the T cell activity needed to fight the disease.' The researchers believe that targeting this protein could be a promising new treatment approach for skin cancer.

The team plans to explore treatments that combine blocking VEGF receptors or adenosine receptors specifically for patients with high HOXD13 levels. They also intend to examine whether these same pathways could be targeted in other cancers where HOXD13 is elevated.
